COMPACTION OF ASPHALT MIXTURES AND THE USE OF VIBRATORY ROLLES

This report summarizes an investigation of compaction of asphalt concrete and compaction using vibratory rollers. The primary objectives of the study were to clarify terminology associated with commpaction and vibratory rollers and to suggest effective operational procedures for vibratory rollers. A literature review was performed in order to gain an accurate understanding of the theory of compaction. The report lists factors affecting the compactibility of asphalt mixtures. In addition, a discussion of mixture problems that affect compaction is presented. A portion of the literature review summarized in this report deals with the background and theory of vibratory compaction. A brief history of the development of vibratory compactors is presented along with current rollers marketed in the United States. Operational terms associated with vibratory rollers are presented and defined. Manufacturers of vibratory rollers were contacted to obtain current vibratory roller specifications and recommended operating procedures. Based on this information, a set of operational guidelines is presented. (Author)
